What is Geographic Information Systems (GIS)?

Geographic Information Systems (GIS) is a technology that creates, manages, analyzes, and maps all types of data. GIS connects data to a map, integrating location data (where things are) with all types of descriptive information (what things are like there). This provides a foundation for mapping and analysis that is used in science and almost every industry. GIS helps users understand patterns, relationships, and geographic context. It is commonly used for urban planning, environmental management, resource allocation, disaster response, and logistics.
